Effects of Preservative on the Meibomian Gland in Glaucoma Patients Treated with Prostaglandin Analogues / 전남의대학술지

This study compared the effect of preservative-containing (PC) and preservative-free (PF) prostaglandin analogue (PGA) formulations on the ocular surface, especially on the meibomian gland (MG) in patients with open-angle glaucoma (OAG). This is a retrospective study of treatment-naïve patients with OAG (n=80) and healthy controls (n=40). OAG patients were randomized into groups using either PC-PGA or PF-PGA for 12 months. All participants underwent ocular surface and MG examinations including their meibum score, meiboscore, and lid margin abnormality score (LAS). Eighty OAG patients were randomized into two groups (n=42 in PC, n=38 in PF). All PGA and control groups showed similar ocular surface and MG parameters at the baseline. Both PC- and PF-PGA groups showed increased meibum scores, meiboscores, and LASs at 12 months compared to the baseline (all p<0.05). At the 12-months visit, PC-PGA group showed severe OSDI, shorter TBUT, greater OSS, and worse MG parameters than those of the other two groups (all p<0.05). In addition, PF-PGA group showed worse meiboscores, meibum scores, and severe OSS scores than those of the control group (all p<0.05). Both PC and PF formulations can cause damage to the MG in patients using PGA. However, PC formulations induced more ocular discomfort, poorer ocular surface, and more severe MG loss compared to PF formulations. Therefore, it would be advisable to use PF formulations in patients with a preexisting or concomitant ocular surface disease or MGD.

Analysis of Intraocular Pressure Elevation after Intravitreal Injection of Ranibizumab and Aflibercept

PURPOSE: To evaluate long-term intraocular pressure (IOP) and risk of IOP elevation after intravitreal injection of ranibizumab or aflibercept in patients with age-related macular degeneration (AMD). METHODS: From January 2013 to December 2016, we retrospectively reviewed patients who underwent intravitreal ranibizumab or aflibercept injections for AMD. IOP was measured before injection and 1 week, 1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 9 months, and 1 year after injection. Sustained IOP elevation was defined when the final IOP increased by 6 mmHg more than the pre-injection IOP, and when there were two consecutively measured values > 21 mmHg. The risk factors were then analyzed. RESULTS: Using Kaplan-Meier survival analysis, sustained IOP elevation occurred in 9 of 80 eyes (11.3%) in 1 year, and the mean survival time was 11.50 months after injection. Five eyes (12.8%) of the ranibizumab group and four eyes (9.8%) of the aflibercept group had mean survival times of 11.39 and 11.61 months, respectively. The log-rank test showed no significant difference between the two groups (p = 0.659). A significant risk factor for sustained IOP elevation was a history of primary open-angle glaucoma (p = 0.035). CONCLUSIONS: The incidence of sustained IOP elevation was not significantly different between the two groups. Clinicians should therefore carefully monitor the IOP before and after intravitreal ranibizumab or aflibercept injections, especially in AMD patients with primary open-angle glaucoma.

Comparison of the Efficacy of Topical Steroids after Trabeculectomy in Patients with Primary Open-angle Glaucoma

PURPOSE: To compare the surgical outcomes and intraocular pressure (IOP) reduction after trabeculectomy in patients with primary open-angle glaucoma (POAG) according to treatment with three different postoperative topical steroids. METHODS: A total of 84 eyes of 84 patients who had undergone trabeculectomy for POAG and were followed-up at least 1 year were included in this study. According to the postoperative topical steroid treatment, the patients were divided into three groups involving 0.5% loteprednol etabonate (LE), 1% rimexolone (RMX), and 1% prednisolone acetate (PDA). The mean IOP change, mean number of topical anti-glaucoma medication changes, 1-year success rate, and complication percentage were compared among the three groups. RESULTS: There were significant reductions in the IOP and number of anti-glaucoma medications during the postoperative 1-year follow-up in all of the groups (all, p < 0.05), but there were no differences among the three groups. Postoperative 1-year success rates (68.2% in the LE group, 67.0% in the RMX group, and 65.9% in the PDA group; p = 0.88) and complication percentages of trabeculectomy were not significantly different among the three groups. CONCLUSIONS: There were no statistical differences in the 1-year success rate, complication percentage, visual acuity, IOP, and number of anti-glaucoma medications among treatment regimens. LE and RMX were as effective and safe as PDA after trabeculectomy in patients with POAG.

Efficacy and Safety of Intracameral Bevacizumab for Treatment of Neovascular Glaucoma

PURPOSE: To evaluate the long-term efficacy and safety of intracameral bevacizumab in patients with neovascular glaucoma. METHODS: This retrospective study included 26 eyes of 26 neovascular glaucoma patients who received intracameral bevacizumab injection between January 2013 and May 2015, and were followed-up for at least 1 year. All patients were treated with topical and/or systemic intraocular pressure (IOP)-lowering medications, intracameral bevacizumab, and panretinal photocoagulation (PRP). The main outcome measures were changes in visual acuity, IOP, and neovascularization of the iris (NVI) and the anterior chamber angle (NVA). To assess the safety of intracameral bevacizumab, corneal endothelial changes were also determined using specular microscopy. Patients whose IOP was uncontrolled received IOP-lowering surgery. Clinical factors associated with IOP-lowering surgery were also investigated. RESULTS: In all patients, intracameral bevacizumab resulted in a rapid and marked reduction of IOP, NVI, and NVA within 1 week. At 12 months after initial injection, 19 of 26 eyes (73%) underwent IOP-lowering surgery. The average interval between initial injection and surgical treatment was 33.6 ± 26.9 days. Baseline IOP (p = 0.018), NVA grade (p = 0.029), and incomplete PRP (p = 0.005) were identified as predictive factors for IOP-lowering surgery. During the follow-up period, there were no statistically significant corneal endothelial changes after intracameral bevacizumab injection. CONCLUSIONS: During 1 year of follow-up after intracameral bevacizumab, the procedure was found to be safe for the corneal endothelium. However, the IOP-lowering effect was transient, and 73% of patients eventually required IOP-lowering surgery. Predictive factors for IOP-lowering surgery were high baseline IOP and NVA grade, and incomplete PRP.

Clinical Features of Dry Eye in Thyroid-Associated Ophthalmopathy According to Disease Activity

PURPOSE: To evaluate the clinical features of dry eye in thyroid-associated ophthalmopathy (TAO) according to disease activity and analyze the related factors. METHODS: This study included 157 patients diagnosed with TAO and dry eye between March 2009 and March 2015. According to the clinical activity score (CAS), TAO patients were divided into inactive (CAS < 3) and active (CAS ≥ 3) groups. Clinical features included age, sex, visual acuity, proptosis, palpebral fissure width, orbital computed tomography (CT) findings, thyroid hormones, and ocular surface parameters including tear film break-up time (TFBUT), Schirmer tests, keratoepitheliopathy scores, and ocular surface disease index (OSDI) were obtained and compared between the groups. In addition, correlations between clinical features and ocular surface parameters were analyzed in both groups. RESULTS: In the inactive and active TAO groups, CAS was 1.24 ± 0.69 and 4.23 ± 1.13, respectively (p = 0.001). Thyrotropin-binding inhibitory immunoglobulin was significantly higher in the active TAO group than in the inactive TAO group (p = 0.048). On orbital CT, extraocular muscle hypertrophy was more common in the active TAO group than the inactive TAO group (p = 0.020). No significant difference was found in age, sex, visual acuity, free T4, and thyroid-stimulating hormone between the two groups. During analysis of the tear film and ocular surface parameters, TFBUT (p = 0.006) was shorter and OSDI score (p = 0.028) was higher in the active TAO group than the inactive TAO group. TFBUT was negatively correlated with proptosis (r = -0.432, p = 0.001; r = -0.308, p = 0.032) and palpebral fissure width (r = -0.367 p = 0.012; r = -0.312, p = 0.031) in both groups. OSDI was positively correlated with proptosis in the active TAO group (r = 0.301, p = 0.033). CONCLUSIONS: TFBUT was shorter and OSDI score higher in dry eye patients with active TAO than in patients with inactive TAO. The TFBUT was negatively correlated with proptosis and palpebral fissure width in both groups.

Risk of Cesarean Section Delivery after Induction of Labor at Postterm Pregnancy in Nulliparous Women / 대한주산의학회잡지

OBJECTIVE: The purpose of this study was to evaluate the risk of cesarean section in nulliparous women who undergone induction at postterm pregnancy. METHODS: The retrospective study was conducted from March, 1997 to March, 2005 by reviewing 331 nulliparous patients more than 41 weeks' gestation delivered after induction at our Hospital. The evaluated variables to assess the risk of cesarean section were maternal age, body mass index (BMI), gestational age (GA), Bishop scores (BS), fetal body weight (FBW), fetal head circumference (FHC) and fetal sex. t-test and x2-test were used to compare these categorical variables. RESULTS: The study included 331 nulliparous singleton pregnant women undergoing elective induction for postterm pregnancy: 127 (38.4%) delivered babies by cesarean section due to induction failure, progression failure and fetal distress, whereas 204 (61.6%) delivered vaginally. The mean maternal ages were 27.59+/-2.57 in cesarean delivery group and 26.99+/-2.61 in vaginal delivery group. The average values of BMI at postterm in cesarean and vaginal delivery groups were 26.70+/-2.82 and 25.75+/-2.67 kg/m2. GA was 41.36+/-0.27 weeks in cesarean delivery group, whereas 41.20+/-0.19 weeks in vaginal delivery group. The average FBW and FHC were 3460.31+/-358.22 g and 34.59+/-1.18 cm in cesarean delivery group, compared to 3363.95+/-361.22 g and 34.03+/-1.34 cm in vaginal delivery group. CONCLUSION: The BMI, FBW and FHC have linked to the risk of cesarean delivery in nulliparous women who underwent elective induction. Thus, these information would provide the useful tools to assess the risk of cesarean section in postterm nulliparous patients for planning an induction.

Clinicopathologic Review of Uterine Adnexal Tumor Torsion / 대한산부인과학회잡지

OBJECTIVE: We analyzed the frequency, clinical symptom, physical exam, site and the degree of torsion, ultrasound findings, histological aspects and the relationship between the pregnancy of ovarian torsion in order to help the early detection of the disease and conservation of the ovary. METHODS: Out of 510 operative cases of adnexal mass patients in Dongguk university hospital from March 1993 to March 2003, 50 histologically confirmed cases of ovarian torsion were selected and retrospectively analyzed. RESULTS: Operative cases of adnexal mass were 510 including the 42 complicated by pregnancy and out of these, torsion occurred in 50 cases (10%) with 16 pregnancy complication. Clinical features of 50 torsion cases are as follows. The frequencies of uterine adnexal tumor torsion were reported by age, 36 cases (72%) in their twenties and thirties, with 21 (42%) nulliparous women at the highest. 42 (84%) had no previous operative history. On the clinical features and physical exam, in the order of frequency, 48 cases (96%) of lower abdominal pain were the highest, and 42 (84%) of GI symptoms, 11 (22%) of urogenital symptoms, and 4 cases (8%) of vaginal bleeding was noted. Under CBC study, 28 (56%) leukocytosis were reported. And on the ultrasound findings, 46 cases (90%) of tumor with hypertrophic wall were noted, septum existed in 12 cases (24%), and 40 (78%) represented internal shadow of the solid portion. The tumor size between 5 to 9 centimeters were the most with 30 cases (58%), and the sum of torsions with 360 and 720 degrees consisted of 40 (78%), occupying for the most of the cases. 27 (55%) of right side existed compared to the 22 (45%) of left. 42 had no previous transabdominal surgery. In the method of operation, 41 (82%) explorative surgeries and 9 cases (18%) of laparoscopic surgery was done, and 5 of these were conservative (12%). The necrosis was noted in 44 cases, and internal bleeding was present in 39 cases. Histologically, functional cyst consisted highest in numbers with 25 (49%), where benign neoplasm with 22, and one malignant neoplasm. About relationship with pregnancy, 9 cases (56%) of corpus luteal cyst were the most. Outcome of the pregnancy was 9 (56%) full term deliveries, 2 abortions (12%), and 1 (6%) preterm delivery. CONCLUSION: Ovarian torsion should be considered when women in between their twenties and thirties with abrupt onset of lower abdominal pain along with nausea and vomiting, leukocytosis, and 5 to 9 cm sized cystic mass with the wall hypertrophy present in ultrasound. Immediate and accurate diagnosis and treatment should follow.

Two Cases of Stroke Occurred in Pregnant Women During the Period of Antepartum and Postpartum: A Case of Cerebral Infarction and the other Case of Cerebral Hemorrhage in Pregnant Women Both without any Manifestations of Preeclampsia or Eclampsia / 대한산부인과학회잡지

While maternal mortality rates due to obstetric causes have declined in recent years, maternal mortality rates due to non-obstetric causes have relatively increased. Among these, pregnancy related stroke is significant because it has the worst impact on both mother and the fetus. Stroke is the state of necrosis in brain tissues caused by perfusion disorder in the cerebral blood flow and pregnant or puerperal women are reported to have about 13-fold more risk of stroke compared to non-pregnant women. Pregnancy-related stroke must be differentiated from stroke in elderly patients, because it is different in pathophysiological etiologies and recurrence rates and also diagnostic and therapeutic methods may affect the fetal health status. In this article, we experienced one case of hemorrhagic stroke occurred in a normal pregnant woman with gestational age of 40 weeks and the other case with ischemic stroke in 33 gestational weeks, those both without any manifestation of preeclampsia or eclampsia.

A Case of Congenital Intracranial Immature Teratoma / 대한산부인과학회잡지

Congenital intracranial teratoma is a very rare tumor. We recently experienced a case of massive congenital intracranial teratoma that discovered in a male infant of 28 weeks of gestation. A 33-year old multigravida was observed at 28 weeks gestation for prenatal ultrasound examination and ultrasonography revealed the fetus was severely macrocephalic with marked hydrocephalus. For therapeutic termination, Hysterotomy and fetal cephalocentesis was performed to deliver a stillborn infant. Autopsy revealed a 2,420 g male infant with severe macrocephaly. A multilobulated intracerebral tumor was found a diameter 18 cm involving both cerebral hemisphere. The tumor was considered to have originated in the vicinity of pineal gland and suprasellar region. Microscopic examination showed the characteristic picture of a teratoma. The predominent component is immature neuroepithelium in the form of primitive neural tubules variably mature somatic tissure from other germ cell layers accompany the neuroepithelium. We report a case of congenital intracranial immature teratoma.

A Report of Pelvic Inflammatory Disease in the Region of the Po-Hang / 대한산부인과학회잡지

OBJECTIVE: Pelvic inflammatory disease has been inclining over the years and high prevalence rates in teenagers is an upcoming issue. Our study is to research and analyze the PID patients of a certain region to give a better perspect of the disease for adequate prevention and management. METHODS: From March 1998 to December 2001, we underwent retrospective studies on medical records of 130 admitted PID patients in po-hang Dong-guk university hospital. RESULTS: Our of all gynecologic patients, 14.4% were PID patients. 17.7% of these were teenagers and patients who were in there twenties consumed up to 50.8%. The disease mostly occured within 8 days of the first menstruational day. Common etiology of the disease was unmarried state, using IUD as a contraceptive and previous artificial abortion. CONCLUSION: PID patients who are in their teens or twenties represented 68.5% of all PID patients. PID in younger ages keeps increasing and seems to be a trend. Secondary treatment of the disease is undoubtfully important, but primary prevention such as sexual education and birth control must also be considered.

A case of Hypertensive Encephalopathy after Postpartum Bleeding / 대한산부인과학회잡지

Hypertensive encephalpathy is defined as severe hypertension in association with headache, nausea and vomiting, visual disturbances, confusion, stupor and coma. The pathophysiological mechanism is incompletely understood and causing as a result of failure of the upper limit of cerebral vascular autoregulation. Magnetic resonance imaging shows a characteristics posterior leukoencephalopathy, predominantly affects the white matter of the parietal and occipital lobes. Hypertensive encephalopathy are potentially reversible with timely and appropriate treatment. We experienced a case of hypertensive encephalopathy after normal vaginal delivery and report this case with a brief review of the literatures.
